  • Welcome information My name is Maciej Dabrowski, I am a PhD Researcher at DERI Galway I work in the MarcOnt Initiative which aims on building tools for collaboriative development of ontologies.
  • Transcript

    1. MarcOnt Initiative Tools for collaborative ontology development Maciej Dąbrowski , Sebastian Ryszard Kruk Digital Enterprise Research Institute National University of Ireland, Galway maciej . dabrowski @deri.org
    2. Outline <ul><li>Motivation </li></ul><ul><li>Ontologies in the world of digital libraries </li></ul><ul><li>MarcOnt Tools </li></ul><ul><li>MarcOnt Portal </li></ul><ul><li>Future work </li></ul>
    3. Motivation <ul><li>World of Digital Libraries </li></ul><ul><li>Identified Problems: </li></ul><ul><li>Interoperability </li></ul><ul><li>Format translation </li></ul><ul><li>Multiple data formats in DL: </li></ul><ul><li>How to support them? </li></ul><ul><li>How to translate between them? </li></ul><ul><li>Who should create mappings? </li></ul>
    4. Real-life problems – user’s expectations <ul><li>Searching: </li></ul><ul><li>Effective and Accurate </li></ul><ul><li>We want correct and fast answers!! </li></ul><ul><li>Intuitive and Simple </li></ul><ul><li>Asking questions should be easy. </li></ul><ul><li>Meaning </li></ul><ul><li>Jaguar – a car or an animal? </li></ul><ul><li>Reasoning </li></ul><ul><li>Give me articles written by students of X in Galway? </li></ul><ul><li>Identified problems: </li></ul><ul><li>Intuitive interface for asking complex querries </li></ul>
    5. Real-life problems - summary <ul><li>Digital Libraries should provide: </li></ul><ul><li>Interoperability </li></ul><ul><li>Support for many formats </li></ul><ul><li>Complex search features </li></ul><ul><li>Intuitive interfaces </li></ul>
    6. Usecase scenario <ul><li>Author </li></ul><ul><li>Title </li></ul><ul><li>Structured resources: </li></ul><ul><li>Author </li></ul><ul><li>Title </li></ul><ul><li>Data storage allows: </li></ul><ul><li>Author </li></ul><ul><li>Title </li></ul><ul><li>Additional information </li></ul><ul><li>cannot be stored!! </li></ul>Author Title Date Title Author Regular Systems Author Title Date
    7. MarcOnt Initiative <ul><li>Motivation: </li></ul><ul><li>Build a bibliographic ontology for </li></ul><ul><li>the Jerome Digital Library </li></ul><ul><li>MarcOnt Initiative goals: </li></ul><ul><li>Deliver a set of tools for </li></ul><ul><li>collaborative ontology </li></ul><ul><li>development </li></ul><ul><li>Collaboration </li></ul><ul><li>Tools for domain experts </li></ul><ul><li>Enable mediation between formats (MMS) </li></ul>
    8. MarcOnt Ontology <ul><li>Central point of MarcOnt Initiative </li></ul><ul><li>Translation and mediation format </li></ul><ul><li>Continuous collaborative ontology improvement </li></ul><ul><li>Knowledge from the domain experts </li></ul><ul><li>Community influence and evaluation </li></ul>
    9. MarcOnt Ontology <ul><li>Goals: </li></ul><ul><li>Capture concepts from the legacy bibliographic formats </li></ul><ul><ul><li>MARC21, Bibtex, Dublin Core </li></ul></ul><ul><ul><li>Lattes, ... </li></ul></ul><ul><li>Create a uniform bibliographic description format for digital libraries. </li></ul><ul><li>Enable the use of Semantic Web technologies (eg. reasoning) to improve capabilities of digital libraries </li></ul><ul><li>Improve interoperability </li></ul>

MarcOnt Tools <ul><li>MarcOnt Initiative involves development of tools: </li></ul><ul><ul><li>MarcOnt Portal – enabling collaborative ontology development </li></ul></ul><ul><ul><li>MarcOnt Mediation Services (MMS) – allows users to retrieve the description of the given bibliographic resource in multiple formats </li></ul></ul><ul><ul><li>RDF Translator – tool for data translation between formats using the set of given mapping rules </li></ul></ul><ul><ul><li>Rulegenerator – allows defining mapping (translation) rules between concepts from different ontologies. </li></ul></ul>
